Sunspot Group 1429 and the Distant Sun (Mar 19 2012)  Image Credit & Copyright: Juan Manuel Pérez Rayego What's that on the Sun? Over the past two weeks, one of the most energetic sunspot regions of recent years crossed the face of the Sun. Active Region 1429, visible above as the group of dark spots on the Sun's upper right, blasted out several solar flares and coronal mass ejections since coming around the edge of the Sun almost a month ago. #astronomy

No sudden, sharp boundary marks the passage of day into night in this gorgeous view of ocean and clouds over our fair planet Earth. Instead, the shadow line or terminator is diffuse and shows the gradual transition to darkness we experience as twilight.

A CME might have delivered a glancing blow to Earth's magnetic field on Jan. 7 - A surge in ground currents in northern Norway suggests that something did rattle Earth's magnetic field

A sweeping prominence, a huge cloud of relatively cool dense plasma is seen suspended in the Sun's hot, thin corona. At times, promineces can erupt, escaping the Sun's atmosphere. Emission in this spectral line shows the upper chromosphere at a temperature of about 60,000 degrees K (over 100,000 degrees F). Every feature in the image traces magnetic field structure. The hottest areas appear almost white, while the darker red areas indicate cooler temperatures. (Courtesy of SOHO/EIT…
